We ­report a ­case of squa­mous ­cell car­ci­noma of the ­lung in ­which a ­left pneu­mo­nec­tomy com­bined resec­tion of the pul­mo­nary ­artery and ­aorta was per­formed ­using a car­di­o­pul­mo­nary ­bypass. The bifur­ca­tion of the pul­mo­nary ­artery was ­repaired ­with a per­i­car­dial ­patch and the ­descending ­aorta was ­replaced ­with an arti­fi­cial ­vessel. ­Eleven ­months ­later, the ­patient under­went dis­sec­tion of the con­tra­lat­eral med­i­as­tinal ­lymph ­nodes ­because of a recur­rence of the dis­ease. ­Even ­though pul­mo­nary metas­tases ­have ­again ­recently ­appeared, he is ­alive and ­doing ­well two ­years ­after oper­a­tion. To ­obtain a ­better prog­nosis in ­cases dem­on­strating an involve­ment of the bifur­ca­tion of pul­mo­nary ­artery, ­more effec­tive com­bined treat­ment ­still ­needs to be devel­oped.
